Adding a certain compound to certain chemical reactions, such as: 51605-32-4, name is Ethyl 5-methyl-1H-imidazole-4-carboxylate, belongs to imidazoles-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 51605-32-4, HPLC of Formula: C7H10N2O2
(1) Ethyl 4-methyl-1H-imidazole-5-carboxylate (7.5 g, 48.7 mmol) was dissolved in acetonitrile (120 mL), N-bromosuccinimide (10.4 g, 58.4 mmol) was added thereto, and the mixture was stirred at room temperature for 3 hours. After the reaction, saturated aqueous sodium hydrogen carbonate was added and the mixture was extracted twice with ethyl acetate. After washing the organic layer with saturated aqueous sodium chloride, it was dried over anhydrous sodium sulfate. After concentrating the organic layer, the residue was purified by column chromatography to obtain ethyl 2-bromo-4-methyl-1H-imidazole-5-carboxylate (3.6 g): 1H-NMR (CDCl3) delta: 4.35 (2H, q, J=7.1 Hz), 2.51 (3H, s), 1.37 (3H, t, J=7.1 Hz).
